WAYNE, INDIANA, A CORPORATION OF COMBINATION PUMP AND TANK.

To all whom it may concern Be it known that we, I)AYID A. COREY andHERBERT J. Gnosvnxon, citizens of the United States, residing at Fort\Vayne, 1n the county of Allen and State of Indiana, have inventedcertain new and useful lmprovements in Combination Pumps and Tanks, ofwhich the following is a specification.

The invention relates to a combination pump and tank adapted to containand dispense liquids and is more particularly adapted to be used forcontaining and'dl's I cover is preferably secured to the tank body"around its pensing liquid cement.

- 1 The prnnary ob ect of the invention is to provide a simple, cheapand efiicient combined tank and dispensing apparatus.

A further object is to provide certain improvements in the mannerofconnecting the measuring and dispensin apparatus or pump with thetank, rend device more simple and cheap in construction and eflicient inoperation as Well as giving the same a more sightly appear-' ance.

preferably strengthened by the metallic outer rim 12 upon which isadapted to rest the C(Hl'llllllttl tank top and pump base. This tank topis preferably formed of cast' metal as illustrated and is preferablynearly circular in form to conform to the coritour of the tank at itsupper extremity, there being around the outer periphery of the plate onthe lower side thereof a circumferential flange 13 adapted to registerwith the interior of the side walls of the tank adjacent the top'to forma closure when the cover is in position. This top periphery by one ormore suitable detachable connections as shown in Figs. 2 and 3, suchconnections consisting preferably of the slotted projections 15 on theperiphery ofthe top plate extending beyond the circumferential flange 12on the tank and the locking bolts-10 pivot-ally connected to the flange12 ofthe tank at 17, there bei'n "winged huts l8ufor insertion on thethreadidfupper extremities of the pivoted bolts 1(5. Heretofore inthe'con'struction of pump tanks it has been the'fcusto'm tomanufact'ureth'e amp and thetank separately and afterwar secure themtogether. Such construction has not onl proved objectionable forseveralreasons tut expensive as Well and in the construction of our improvedpump and tank the top is specially constructed with a view to utilizingthe same as a partbf the pum specialsu'pport to various moving t 1e pumpas the control mechanism.

The top cover of the tank is provided with perforations for the verticalreciprocating iston rod 19, Fig. 3, and for the vertical disc large pipeof the pump, which latter is indicated by the refercncecharacter 20. Theopening for the piston rod is surrounded by a circular depending flangeon the under side of the plate as indicated at 21, the same being ofsutlicient diameter and provided with an interior enlargement to receiveand furnish a seat for the upper end of the pump barrel 22 which is oftubular form, preferably of l)l2l S. At the lower extremity of the pumpbarrel within the tank is the usual piston rod andthe pump I valvecasing indicated by the reference character 23 and provided with aflanged portion as lndicated and fog furnishing parts of Patented Sept.8, 1914.

at 24 adapted to receive and a chamber for the inlet close the lowerextremity of the pump barrel. The valve casing irregular form providingan inlet at 25 and valve 26 which is of the usual puppet type of valveor of any desired construction of lift valve adapted to control. theopening leading from the inlet 25 to the piston chamber, the pistonbeing secured to the lower extremity of the piston rod 1'9 and being ofany desired construction but without any valve controlled or otheropening to permit the passage of liquid above the piston in the pumpbarrel, since it is desired to discharge the liquid from below thepiston through the valve 27 which opens when the pressure of the pistonupon the liquid within the pump barrel closes sure from the descendingpiston to pass upwardly through the discharge pipe 20 of the pump andthrough the valve controlled nozzle 28 to be discharged from the pump.The cast top cover of the tank isfurther provided with a boss on theunder side in the form of the peripheral flange 29 surrounding theopening for the discharge pipe 20. The member 29 is constructed as shownwith an opening somewhat larger than the outside diameter of the pipe 20and interiorly threaded to receive the upper extremity of the threadedcollar 30 which is adapted to be rigidly secured to the discharge pipe20 by set screw 31. By this construction the discharge pipe 20 may berigidly and securely fastened to the cover plate of thetank. Itssecurement is further effected by means of pump bracket 32 secured tothe cover at its bottom by bolts as indicated at 32, the said bracketbeing provided with a housing to receive the upper extremity of the rack33 which is secured to and operates the piston rod. Within the housingat the top of bracket 32 through which passes the piston rack bar thereis journaled the usual pinion on shaft 8i adapted to be actuated by theusual handle 35 for imparting reciprocatory movement to the piston rodthe gear itself not being shown since it forms no part of the presentinvention. The upper extremity of the bracket Z12 is provided with anintegral collar adapted to surround the upper extremity of the dischargepipe 20 being secured to the said pipe by set screw as indicated at 36or other suitable means.

The valve casing 23 at the bottom of the pump barrel within the tank isprovided with a housing at the discharge side of the casing which opensupwardly and is interiorly threaded. \Vithin this housing the valve cag37 may be rcmoyably secured and locked in position by the hollow sleeve38 which is suitably threaded. at its lower extremity for sccureiuent tothe valve casing 2 and at its upper extremity preferably given ahexagonal shape and provided with is preferably of an i tic-n may theinlet valve 26 and permits the oil under presa threaded opening forsecurement to the threaded lower extremity of the vertically extendingdischarge pipe 20. The valve casing 23 is supported from the top coverby the vertical rods 23 screw threaded at their upper extremities intothe top cover and passing downwardly through the valve casing 23 beingthreaded at their lower extremities and provided with nuts.

By casting the tank cover of sufficient thickness to give it thenecessary strength it will be seen that the entire pump construcbe verysecurely fixed in relation to the tank furnishing a much simpler, moreeconomical and more durable construction than where pump and tank coverare sepaconstructed. It is prerably and detachably ferred that incasting the depending peripheral flanges 21, 29 for the discharge pipe20 and for the piston rod and the pump barrel, the material may be castsolid between the flanges to afford a suitable support for a hole inwhich may be rotatably journaled the lower extremity of piston controlrod 39, the upper end of which is likewise journaled in the upperextremity of bracket 32, this rod being provided with the usualadjustably mounted control fingers 40, 41, for limiting the throw of thepiston rod by an gaging means as the fixed member 42 on the rack arSurrounding the opening in the top cover plate for the piston rod 19 ispreferably cast integrally with the plate an upwardly extending flangeforming a suitable pacle ing gland around the piston rod, as indicatedat 43, the same being threaded exteriorly to receive clamping nut-i-'lwhich cooperates to bind the upper member -15 of the gland uponsuitable packing material contained within the gland. In order that thetop cover of the tank may be liquid tight, suitable packing as indicatedat '46 may be placed around the discharge pipe 20 at the point it passesthrough the cover between the cover flange 29 and the threaded lockingmember 30 to close the joint between the cover and the pipe at thispoint. For filling the tank without removing the top cover plate anopening in the cover plate, as indicated at 47. may be provided, thisopening to have a cover as indicated at 48 secured by means of wingednuts and cooperating bolts as shown in Figs. 2 and i). The exterior boltand nut may be an extension of one of the hinged bolts 16 with itswinged nut 18 while at the inside separate fastening means as indicatedat 49 provided.

A vent pipe 51 is secured in any suitable manner to the cover and a T 50is preferably mounted upon the outer end of the vent pipe 5]. the openends of the T being provided 1 with screens 5; and .33. which may be Man desired or suitable reticulated material and which are adapted topermit the egress of 1,1o9,ees

vapors and gases from a tank and to prevent the ingress of objectionablematerials, as well as to prevent fire from entering the tank. I

The operation of the device does not differ from that of the ordinarypump tank, the material to be dispensed being introduced through theopening beneath the removable cover 48 and discharged through the pumpnozzle by the operation of the pump iston actuated by handle 95, theamount of iquid to be dispensed bring predetermined either by limitingthe operation. of A the piston through the control rod 39 and stopsthereon or by the number of total reciprocations of the piston or bycombination of total reciprocations and fractional measurements due tolimitin the movement of the piston by the contro 1' means described.

It is not desired to be limited to the exact details of constructionsince it will be a parent that certain modifications may e adopted bythose skilled in the art without departing from the purpose and spiritof the invention. I

We claim d y In a liqui ispens' a aratus the combination with a closedtani oi a sin 1e cast metal coventherefor formed with a e ending flangeto fit the inside vof the tan the annular said cover being provided withopenir s therethrou h, some of said openings being surroundecf above andbelow the cover with rojections formin packing gland cases an one ofsaid openings being adjacent the periphery of said cover, the edges ofthe cover being formed with slots, hinged clamping bolts secured to thetank adjacent the topthereof and adapted to be pivotally swung into engaement with the slots of said cover, winge nuts to engage said bolts tobind the cover in position and a lid for the said opening adiacent theperiphery of the cover ada ted, when in closed position, to be engagedon one side by one of the winged nuts for securing the cover inposition, and a separate winged nut inserted through the other side ofthe lid into the cover for securing the lid firmly in position.
